Battery removal method based on floating platform

Abstract

The invention provides a floating platform based battery dismounting method. The method includes the following steps: a step of floating alignment unlocking, namely the step of lifting a locking device on a floating platform, wherein the floating platform can float in all directions after being in contact with a battery assembly so that the locking device can be inserted into a latching mechanismon the battery assembly or a latching mechanism on a vehicle bottom battery fixing structure; a step of floating locking, namely the step of making the floating platform cannot float and form a rigidbody with a clamping mechanism so that lateral force that the floating platform recovers a balanced position can be eliminated; and a step of battery unlocking, namely the step of unlocking the battery assembly and the vehicle bottom battery fixing structure, wherein the battery assembly can descend with the floating platform so that the to-be-charged battery assembly can be transferred to a transferring device. The method is ingenious in design and rigorous in logic, so that an electricity exchange platform can float in all directions, the positioning requirements of the electricity exchangeplatform can be reduced, the lateral force generated during floating can be eliminated, and the occurrence of unnecessary bumping of the battery assembly can be avoided; and the requirements of rapidelectricity exchanging for new energy vehicles can be met, and convenient popularization and application can be realized.

Description

Technical field[0001]The invention belongs to the field of quick battery replacement, and specifically relates to a battery disassembly method based on a floating platform.Background technique[0002]With the increasing use of various types of new energy vehicles such as electric vehicles and hybrid vehicles, technologies related to battery quick change have become more and more subjects of concern and research. How to provide electricity supply for electric vehicles with insufficient electricity in a timely and effective manner has become an issue of great concern to manufacturers and car owners. The method of replacing electric vehicles by establishing a battery swap system, that is, directly replacing the exhausted power battery with a fully charged power battery, can complete the supply of electric energy within minutes, so the battery swap method is a kind of Very efficient way of power supplement.[0003]In the process of battery exchange through the battery exchange system, the b...

Problems solved by technology

[0003] In the process of battery replacement through the battery replacement system, the battery pack at the bottom needs to be replaced accurately, and the position of the vehicle or the battery replacement platform needs to be adjusted. However, when positioning and adjusting the vehicle or the battery replacement platform, it is inevitable. There will still be errors. In order to make the positioning and alignment actions go smoothly, the target object needs to be able to float freely, that is, the contact surface between the power exchange platform and the battery pack and the support surface that is in contact with the vehicle need to be floatable, but in the horizontal direction During the floating process, it is very easy to deviate from the middle position and generate a lateral force back to the center, which makes unnecessary bumps on the electrical connectors during the battery disassembly process, which affects the battery life
